    First, PC and Macs shut down the hard disk during sleep, which reduces the heat inside the box.

    Second, the 622 doesn't do much in the way of 'sleeping' even in standby.

    You got lucky with your first 622 lasting that long with the way you have it installed. You don't have nearly enough room on the right side to allow for good airflow. You need to correct that.

    Or you can keep posting and showing why you are right and everyone else that has tried to help is wrong. The only downside is that you will probably keep having these problems with heat.

    It is your choice.

    Funny, the first pictures show the unit tight against the right side, and the second picture shows 1" of space, which isn't nearly enough space.

    I guess you aren't going to get the actual data from the DVR, you are going to continue the "it feels like it's 100 degrees" line. My temps are, 120-high, 104-average, and 87-low, this is hard data from the DVR. Keep insisting the DVR is at fault and don't follow any guidance that has been offered.

    Have fun replacing the DVR every six months................................

    Hey, I'm just quoting the engineers who designed it, what do I know?

    For optimum long time performance the 622 needs active air management.

    Place a small fan on the left end of the unit pulling air out of the left side and leave at least 2 inches open space on the right side.

    I believe the 722 has a small amount of active air mangement. Last week we were in Dallas at my daughters house. Tey have a 722 an I could actually feel a flow of warm air out the left side of the unit. That has never happened with my 622. I guess the made a small alteration to the 722 so the internal fan runs all the time.

    Jim, it's doesn't look that way - both models running same FW, but bigger disk inside of 722 would create more heat and trigger FW for turn on the fan.

    Something to think about...

    For anyone that thinks 1 inch of space is enough for circulation...

    Put a box (no plastic bags please) over your head that only allows 1 inch of space around your head. You should find it more difficult to breathe than normal due to the restricted airflow.

    Now imagine your were running around hot and trying to breathe in that.

    1 inch of space for the intake might as well be nearly zero for the effectiveness factor.

    As to why previous units functioned in that space... not all things are created equally... some receivers probably can take more abuse than others, but continual abuse is not the answer.

    i really appreciate evreyone input and gave advice on how to keep the temp in check. i just want to point out that the unit did not have a good design to last for years. leasing one is ok but own one like this??? no way.

    This is likely not the case at all. Newer drives, regardless of size, often consume less power.

    As an example, the Seagate Pipeline HD drives typically eat less than 4W while the drives used in the ViP622 were somewhere upwards of 6W as I recall. The drives are one of the lesser producers of heat in the system while remaining one of the more sensitive.

    I would recommend you to compare power dissipation parameters for both real Seagate models - 320 GB in 622 and 500 GB in 722, that will help return the discussion to correct path and will cut speculation just for speculation.

    All I know is I could put my hand down about 1 inch from the outlet vents on the left side and feel a flow of warm air out of the 722, I have never felt that on my 622.

    The fan was definitely running at a low speed, on my 622 it runs only at reboot.

    If you could put flashlight at vent on right side and check if the fan rotating ...

    So all my equipment (I have a 622) is in a cabinet that is recessed into the (un-air-conditioned) garage, which does get QUITE warm at this time of year (120+ probably). I have about 2" on both the left and right sides and no auxillary fan.

    Last year I had one overheating warning with my 622, but none this year. Yesterday's temps: H141, L114, A129.

    Thoughts anyone? Or just leave well enough alone?

    You're sitting borderline where failures usually happen. To be safe, I'd find a way to cool it, if even just 5 - 10 degrees.

    Just make maximum airflow what you could. At least internal temp will be at ambient level, not plus 20°F to that. If you could - open a cover and add 80mm fan (12 V would be OK) what could draw current from 622's USB port ( up to 100 mA ).

    So should a fan be aimed down the left side (where air exits) or down the right side, where air enters? I would think at the exit...:flaiming

    And I'll get one of those USB fans at the beginning of this thread.

    Cool it. The specifications for many modern hard drives puts the top of the operating temperature range at 129F. Operating for long periods above that temperature will likely reduce the lifetime of the drive accordingly.

    So as a leased receiver, am I "allowed" to open the box?

    In September 2008 when I added a 612, I moved my 722 out of the component cabinet onto the top of another cabinet 32 inches from the 612 with plenty of air flow. But in the past two weeks it's been hot here and the room temperature every afternoon rises to about 85±, then slowly cools overnight.

    Two days ago I dug the laptop cooler I used in the component cabinet out of the closet and put it under the 722, as every day the internal fan started running on high about 5:15 or 6:15 pm, 15 minutes after it started recording and the average internal temp had started crawling up. I turn the laptop cooler fans on at 5 pm. Then the internal fan seems to not turn on and the 722 case doesn't get warmer then the ambient air.

    In the end, it appears to me that the one major design flaw of the 622/722 units we will all remember someday was inadequate cooling.

    The 612 doesn't seem to have this particular problem and I would guess that the 722k doesn't either.

    "I would guess that the 722k doesn't either." - umm, did you noticed last two pictures above shows one 722k and other 722 ?!

    So as a leased receiver, am I "allowed" to open the box? - well, other ppl did that; so if you have same skills, why not ? It would prevent you from loosing your time and recordings then Dish from spending for tech time and other DVR for swap it.
